IMPROVEMENT IN PRocEssEs FOR FLAVORING uQuoRs.

Specification forming part of Letters Patent No. 205,443, dated June 25, 1878; application filed.

A January 29, 1878. i i

To all whom i-t may concern:

Be it known that I, JOHN HENRY THIER- MAN, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Process of Flavoring Alcoholic Liquors; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to use the same, reference being had to the accompanying drawing, which forms a part of this specification, and in which is shown a vertical section of a filtering apparatus such as I prefer to use for the purpose of carrying outmy improved process.

As will be seen by reference to the drawing, this apparatus is constructed as follows:

A is a cylinder, constructed of any suitable material, and provided with a perforated false bottom, I), raised upon supporting-bridges b I). On top of this I place a woolen blanket, a, stretched and pressed closely against the inner walls of the cylinder by a ring, 0, of copper wire or other suitable material. a is another similar blanket, held by a ring, 0, restin g upon shoulders or brackets 01 upon the inner walls of the cylinder. The lower twothirds of the cylinder is thus divided into two compartments, B B, each of which is filled or packed with a mixture of ordinary rectifyingcharcoal and finely-ground filtering-paper.

Above and resting upon a blanket, a which covers the charcoal in the upper chamber B, I place a cover or partition of perforated sheet metal, 0, which serves to hold the charcoal and blanket a in position, and is itself held firmly in its place by a brace, D, consisting of two rings, 0 and 0 connected by standards 3 s, the upper ring of which rests against the top or head of the cylinder, which forms its cover. The lower ring rests upon the partition 0, and thus an empty chamber, E, is provided, into which I introduce the prepared flavoring ingredients.

F is the top of the cylinder, having a circumferential flange, e, corresponding with a similar flange, e, at the top of the cylinder proper. Below this flange I place a ring, f, of iron or other suitable material, the edge of which projects beyond the flange. After placing the head upon the cylinder '9. packin g-ring, i, of rubber or similar material, being interposed, Iadjust aring, f, similar to f, over the flange e. The rings ff have perforations for bolts g g, by which they are united, thus securing the cover upon the cylinder. There he in g no perforations or bolt-holes in the flanges c e, the cover fits absolutely tight.

The top of the cylinder F has a central opening, G, with upward -projectin g shoulders, through which I introduce the flavoring ingredients into the chamber E, over which opening I adjust, by means of male and female threads, a screw-cap, H, with a packing of rubher or other suitable material interposed.

J is the induction-pipe. It enters the cylinder near the top, and is provided with a cock, h, for regulating the flow of the liquids. A convex screen or sieve, j, covers the perforation through which the liquid enters the cylinder, and prevents any of the flavoring ingredients or agents from entering the induction-pipe J. K is the exit-pipe, which conducts the flavored liquids out of the cylinder through a perforation below the false bottom, which is also provided with a cock, 7r, for regulating the flow of liquor.

The inner metallic walls of the cylinder, and all metallic surfaces of all parts of my flavoring apparatus which come in contact with the flavoring oils or essences, or liquids charged therewith, I cause to be thoroughly tinned or glazed, to make them. resist all corrosive action.

To carry out my improved process I first saturate thoroughly a quantity of finelycomminuted rectifying-charcoal with the particular essential oil the flavor of which is to be imparted to the liquor. All kinds of essential oils may be used with my process, such ascaraway-seed oil, oil of juniper, bergamot-oil, 850.; and my process is particularly applicable to essential oils of a highly-volatile nature. The saturated charcoal is placed through the opening G in the emptychamber E, which is then hermetically sealed by adjusting the screw-cap H, when the process of flavoring should be commenced with as little delay as possible. Immediately following the flavoring process the filtration or rectifying of the liquor or liquid takes place by its precipitation through the filtering medium below, thus per-' forming the flavoring and rectifying of the liquor at a single and continuous operation.

In operation the liquid first passes into the flavoring-chamber E, Where it becomes charged with the oil or essence prepared as described, and is conducted thence through the packing of charcoal and filtering-paper in the compartments B B. In its passage through these packings the oil or escence is perfectly dissolved and neutralized, and the liquid becomes evenly and thoroughly impregnated With the most delicate desired flavor.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The herein-described process of iavo and rectifying alcoholic liquors, consisting first, in introducing the liquor into contact with charcoal impregnated with the essential or flavoring oil or extract; and, secondly, in

precipitating it through filtering medium be 10W, whence it is drawn off, thus flaw ring and rectifying the liquor at a single continuous op
